This system is designed for the customer that wants an inexpensive system to air up tires. The air hose simply threads directly into the preset regulator for a completely hassle free setup. You can customize this system by adding some fittings like an automatic quick disconnect and/or a 45 degree fitting to so you can remove the hose. This EC regulator used in this system is the same preset regulator we've used for over six years on our old systems and had excellent results!! This is a great quality starter system at an affordable price. Save money now and upgrade this system later when you need to! You will be hard-pressed to put together your own system with the same quality components for less!!
